Ios8 如何使用FBSDKShareKit将iPhone应用程序中的图像和视频共享到facebook

我不熟悉ios开发，如何使用FBSDKShareKit将iPhone应用程序中的图像和视频共享到facebook

    FBSDKSharePhoto *photo = [[FBSDKSharePhoto alloc] init];
    photo.image = [UIImage imageNamed:@"1.JPG"];
    photo.userGenerated = YES;
    FBSDKSharePhotoContent *content = [[FBSDKSharePhotoContent alloc] init];
    content.photos = @[[FBSDKSharePhoto photoWithImage:photo.image userGenerated:YES] ];
    //content.photos = @[photo];

    // Assuming self implements <FBSDKSharingDelegate>
    [FBSDKShareAPI shareWithContent:content delegate:nil];

有人能帮我吗？提前谢谢。

请详细解释您的问题。你有错误吗？我需要一些例子在fb上分享图片
